Cursor's Vercel Stack Unifies Sites and Boosts Growth 5%
Cursor unified four web properties (marketing, dashboard, docs, help) under cursor.com using Vercel Microfrontends for zero-downtime migration of 100+ routes, Flags + Statsig for seamless A/B tests that lifted PLG signups 5%, and agent-driven code publishing over CMS.
Migrate Multiple Sites to One Domain with Progressive Microfrontends
Unify disparate web properties like marketing sites, dashboards, docs, and help centers under a single domain (e.g., cursor.com) without downtime by leveraging Vercel Microfrontends. This integrates separate repos into a consistent experience, preserving revenue-critical flows like signups during launches.
Execute in phases: launch new marketing site first (20 core routes), then migrate docs from docs.cursor.com to cursor.com/docs, and finally the help center. This scales to 100+ routes across four properties. Trade-off: maintains team velocity in isolated repos while standardizing branding and domain authority, which supports SEO and global expansion from 4 to 11 languages.
Result: Enables fast launches (e.g., new brand in September) without breaking auth/signup, as microfrontends bridge marketing pages and product flows seamlessly.
Build Low-Latency Experimentation Loops with Flags, Edge Config, and Statsig
Optimize PLG funnels and content by combining Statsig for experiment definitions, Vercel Flags SDK evaluated via Edge Config for sub-50ms latency, and build-time pre-computation to eliminate flicker/layout shifts.
Test high-impact elements: hero copy ("download" vs. "get started"), nav additions like "Contact sales" (increased sales conversions and PLG signups 5%), country-level localization, tier recommendations, and geo-targeted logos/case studies. Prioritize healthy SEO/AEO, fast loads, and seamless rendering.
This shifts from product hyper-focus to data-backed iteration on onboarding, especially as sales motions expand. Pre-compute versions at build time for smooth experiences, trading build duration for runtime performance—ideal for marketing sites without prior A/B testing.
Automate Content Publishing with Agents in Code, Ditch CMS Friction
Replace CMS with Markdown-in-code + AI agents for faster updates that align with engineering workflows. Agents handle first-pass edits via Slack (e.g., "@Cursor, make this fix"), open GitHub PRs, generate Vercel Preview Deployments, and even preview videos via computer use for before/after testing.
Proof: Migrated CMS content using 200 parallel agents over 3 days ($260 token cost), self-testing and iterating autonomously. Once codified as reusable skills, changes become seamless—team-wide participation without CMS logins or manual loops.
Impact: Reduces friction as surface area grows, empowers non-specialists via Slack requests and previews, and compounds speed post-setup. Avoids CMS slowdowns that force human intervention, fitting agent-heavy teams.
